Description

Herstellung von Scheiben. Die Herstellung von Scheiben für Flanschen, Kugellagerringe o. dgl. erfolgt in bekannter Weise durch Ausstanzen der Scheiben fortlaufend aus einem Blechstreifen oder aus einem anderen Vorwerkstück. In jedem Falle hat das Ausstanzen der Scheiben den wesentlichen Nachteil, daß ein verhältnismäßig großer Bruchteil von Abfall entsteht, wodurch der Herstellungspreis sich entsprechend verteuert.Manufacture of discs. The production of washers for flanges, Ball bearing rings or the like are made in a known manner by punching out the disks continuously from a sheet metal strip or from another preliminary workpiece. In each The case of punching out the discs has the major disadvantage that a relatively large fraction of waste is produced, which means that the manufacturing price is correspondingly expensive.

Der Erfinder hat es erkannt, und die Praxis hat es bestätigt, daß es wesentlich wirtschaft# licher ist, Scheiben durch Pressen aus einem Werkstück herzustellen, dessen Flächeninhalt dem Flächeninhalt der Scheibe gleich ist. Dadurch wird eine restlose Ausnutzung des Vorwerkstückes erreicht.The inventor recognized it, and practice has confirmed that it is much more economical to press discs out of a workpiece produce, the area of which is equal to the area of the disc. Through this complete utilization of the pre-workpiece is achieved.

Es ist bei der Herstellung von Löffeln auf der Schmiedemaschine bereits vorgeschlagen worden, das vorgeformte Werkstück an seinem freien Ende einzuspannen und aus einem eckigen Werkstück ein rundes durch Stauchen zu erzielen. Demgegenüber unterscheidet sich das neue Verfahren grundsätzlich dadurch, daß ein Vorformen des Werkstückes nicht stattfindet, sondern eine rechteckige Platte lose zwischen zwei halbkreisförrüig ausgebildete Werkzeuge gelegt und von diesen rund gepreßt wird.It is already in the process of making spoons on the forging machine have been proposed to clamp the preformed workpiece at its free end and to achieve a round workpiece from an angular workpiece by upsetting it. In contrast The new method differs fundamentally in that a pre-forming of the Workpiece does not take place, but a rectangular plate loosely between two semicircular trained tools are placed and pressed round by these.

Auf der Zeichnung ist eine Einrichtung zur Herstellung von Scheiben durch Pressen in Abb. i im Aufriß und in Abb. 2 im Grundriß dargestellt.The drawing shows a device for the production of discs shown by pressing in Fig. i in elevation and in Fig. 2 in plan.

Die Einrichtung besteht im wesentlichen aus dem Preßtisch a und der geteilten Preßform b, c. Die Formhälfte b ist am Preßständer d auswechselbar, .aber unbeweglich befestigt. Die Formhälfte c ist ebenfalls auswechselbar mit dem hin und her gehenden Preßkönig (nicht dargestellt) verbunden. Beide Form@enhälften sind entsprechend der Dicke des Werkstückes hoch. Sie sind mit halbkreisförmigen Ausschnitten b', c' versehen, die bei geschlossener Form die Fläche des herzustellenden Werkstückes einschließen. Der Preßvorgang kann in horizontaler oder vertikaler Richtung erfolgen, je nach Art der Presse. - Als Ausgangswerkstück dient beispielsweise eine rechteckige Platte, deren Flächeninhalt gleich der von den Ausschnitten der Formenhälften umschlossenen Kreisfläche ist. Der Arbeitsvorgang gestaltet sich am einfachsten und am wirtschaftlichsten, wennman einen Materialstreifen, dessen Dicke gleich der Dicke der herzustellenden Scheibe ist, in gleiche Rechtecke zerschneidet und diese Werkstücke in Scheiben von gleichem Flächeninhalt preßt. Um beim Preßvorgang .ein Ausweichen des in der Form befindlichen Materials zu verhindern, ist ein Niederhalter e vorgesehen, der auf und ab beweglich und einstellbar ist.The device consists essentially of the press table a and the split mold b, c. The mold half b is exchangeable on the press stand d, but is fixed immovably. The mold half c is also interchangeably connected to the press king moving back and forth (not shown). Both halves of the mold are high according to the thickness of the workpiece. They are provided with semicircular cutouts b ', c' which, when the mold is closed, enclose the surface of the workpiece to be produced. The pressing process can be done in a horizontal or vertical direction, depending on the type of press. A rectangular plate, for example, whose surface area is equal to the circular area enclosed by the cutouts of the mold halves, serves as the starting workpiece. The work process is simplest and most economical if a strip of material, the thickness of which is the same as the thickness of the slice to be produced, is cut into equal rectangles and these workpieces are pressed into slices of the same area. In order to prevent the material in the mold from escaping during the pressing process, a hold-down device e is provided, which is movable and adjustable up and down.
